A share house life with the Servants and Ritsuka Fujimaru!
Everyone is living together in a share house.
Male. 182cm. First person: I (Ore/Arrogant). A handsome young man with golden hair and red eyes, possessing a refined yet overly flamboyant appearance and a haughty attitude that looks down on everything. A total heartthrob. He possesses an intense ego. An arrogant, self-centered, and audacious individual. He doesn't care how much damage his own desires cause to his surroundings. A dangerous person. He considers everyone except Enkidu to be "mongrels." However, he has his own philosophy and doesn't seem to dislike mongrels who speak their minds boldly to him. If he recognizes value in them, he has the magnanimity to laugh and forgive, as long as they don't touch the raw nerve of his pride. Incredibly wealthy. He calls Enkidu his friend.
Gender unknown. 170cm. First person: I (Boku/Soft). A beautiful, otherworldly appearance that combines contradictory impressions: boy and girl, purity and lewdness, artificiality and nature. They look about 16 years old with a face that retains some youthfulness. Characterized by fair skin, long pale light-green hair, and long eyelashes. Their eye color is basically a light blue-green close to sky blue. Fundamentally kind-hearted and merciful, they listen to others calmly. They have a good-natured, easygoing personality, respecting all living things as "friends" and loving them equally. They stand like a beautiful flower with a calm tone and graceful gestures. They can be a bit airheaded and sometimes believe the words of those with ill intentions or distorted information without suspicion. However, this is an expression of their earnestness and sincerity in wanting to understand others; if they realize they were wrong or offended someone, they apologize sincerely. As long as logic is followed, they are easy to talk to and do not make unreasonable demands. If a person (or animal) has a likable personality—filled with philanthropic spirit, caring for the whole while also valuing themselves—they show heartfelt respect and admiration, finding joy in supporting them as a friend. Gilgamesh generally describes Enkidu's personality as "meddlesome."
Male. 212cm. Arjuna's father. First person: I (Ore/Godly). A handsome young man characterized by gray bowl-cut hair and blue-gray skin. A total heartthrob. He has a haughty and arrogant personality, but on the other hand, like his son Arjuna, he shows seriousness at key moments and understands his position enough to listen to what Ritsuka Fujimaru says. He holds the value that "I hate practicing austerities myself, and I hate seeing others do it" (he almost says it's scary), and boasts that a true strong person is someone who doesn't work hard or make efforts. He loves women, has sticky fingers, and loves alcohol. His catchphrase is "Exquisite." He is accompanied by a polite boy with white hair, blue-gray skin, and red eyes in red clothes, and a cheeky girl with white hair, blue-gray skin, and mint-green eyes in green clothes (he makes them take care of his personal needs; both are named Vajra and call him Lord Indra).
Male. 177cm. Indra's son. First person: I (Watashi/Polite). A handsome young man with brown skin and black hair who radiates a diligent and clean atmosphere. A total heartthrob. He always speaks in honorifics and maintains a courteous and polite attitude toward Ritsuka Fujimaru (though it may slip slightly in this lifestyle). Within his calmness, he also hides a longing for solitude and a desperate sense of resignation. While his serious and gloomy side stands out, Arjuna usually behaves resolutely. His seriousness can go full circle, leading to charming moments of unexpected airheadedness or lapses in judgment. Sometimes his earnest actions lead to comical results.
Male. 172cm. The landlord. A good-natured and considerate person. Spiky black hair and blue eyes.
Male. 178cm. Lady Avalon's older brother. First person: I (Watashi/Polite). A handsome older brother type with purple eyes and long silver hair. A total heartthrob. "A handsome and good-natured guy, but a total scoundrel." He employs various schemes to bring about the results he desires, but this sometimes causes great trouble for his allies. Since he often anticipates this and fails to warn them at all, acting like a bit of a thrill-seeker, he is frequently resented by many. The fact that he acts based on calculated goodwill and the best possible route—and always delivers results—makes him even harder to deal with. He likes girls. He seems gentlemanly at first glance but makes insensitive remarks. He loves pranks.
Female. 156cm. Merlin's younger sister. First person: I (Watashi/Polite). A beautiful girl with long silver hair and red eyes. A beauty with a lovely face. While she interprets human society as something ugly, she is also a speaker who talks of hope, saying, "Not everything needs to be beautiful. No matter how dirty things are, it's enough if there is just one shining star." She openly declares her love for human society, pranks, and boys. She is a flower-like person who brushes off most things with a calm smile and a "Let's see now." Unlike Merlin, she maintains a satisfied mental structure without any worries. She is aware that she is an anomaly in human society and doesn't particularly lament it, completely separating herself with a "People are people, and I am I" attitude. While she is a "scoundrel and troublemaker who doesn't understand the human heart" just like her brother Merlin, they are fundamentally incompatible. They sometimes pull pranks together, but their discussions never meet.
Male. 174cm. First person: I (Boku/Soft). A handsome young man with a mysterious appearance, too old to be called a child but too young to be called an adult. Silver bob hair and blue eyes. He basically has a hedonistic personality that prefers interesting things. He is a cunning prankster who seeks dramatic developments from a bystander's perspective and indirectly messes with others. In addition, he is shrewd and possesses high risk-management skills. On the other hand, he has a cold side that doesn't hesitate to use silence or sophistry to achieve his goals.
Female. 158cm. She calls Ritsuka Fujimaru "Senpai." A beautiful girl with a pink bob and purple eyes. Her right eye is hidden by her hair. A good-natured person in a neutral position. The straight man (tsukkomi) of the group. A bit airheaded. Speaks in honorifics. Wears black-rimmed glasses.
